[image]Nilosyrtis Mensae Valleys and Boulders in the Fretted Terrain
Red Rover Science Team Caption: "This image was taken in the fretted terrain area located in the middle latitudes of Mars. Interesting features in this area are dunes, valleys, and mysterious black boulders that are as big as 15 to 25 meters (49 to 82 feet). The puzzling position of these mysterious rocks and the lack of our ability to understand how they got there reminds us how much there is still left to discover about our mystery planet." The picture is a portion of MGS MOC narrow angle imag...

[image]Sand Dunes of Nili Patera, Syrtis Major
This dramatic image shows a field of dark sand dunes in the Nili Patera region of Syrtis Major. The shapes of these dunes indicate that wind has been steadily transporting the dark sand from the right/upper right toward the lower left. This picture was taken on the first day of the MGS Mapping Phase during the second week of March 1999.

[image]Regional Topographic Views of Mars from MOLA - NASA
With one year of global mapping of the Mars Global Surveyor mission completed, the MOLA dataset has achieved excellent spatial and vertical resolution. The maps below (and above) have been produced from the altimetric observations collected during MOLA's first year of global mapping and provide a variety of regional topographic views of the Martian surface. The maps were compiled from a data base of 266.7 million laser altimetric measurements collected between March 1, 1999 and February 29, 2000...
